Pippa Middleton's new relatives are reality stars and race car drivers

England's most eligible bachelorette is officially off the market, but she's definitely inherited a very interesting new family.

Pippa Middleton got engaged to hedge fund manager, James Matthews, 40, late last week in an incredible hilltop proposal in the Lake District and now sources are calling her impending nuptials the biggest wedding in England since her sister Kate Middleton's royal wedding to Prince William. And since it'll definitely be one of the most-watched events, it's time to get to know Pippa's soon-to-be family members.

Spencer Matthews: Future brother-in-law

Pippa is about to get a reality star brother-in-law. Spencer, who once claimed at 25 years old that he'd slept with more than 1,000 women, is one of London's most notorious party guys. He's starred on Britain's version of "The Bachelorette," and became famous on the show "Made in Chelsea" about rich 20-somethings living in the posh London neighborhood. He even wrote a memoir titled, "Confessions of A Chelsea Boy." Last year, he left the show I'm a Celebrity ... Get Me Out of Here! (out of the jungle!) after revealing he was addicted to steroids.

David Matthews: Future father-in-law

The former race car driver turned used-car entrepreneur now owns one of the swankiest hotels in St. Barthd, Eden Rock. He bought the hotel in 1995 with his wife, Jane, and they moved their family there to enjoy more fun in the sun and an adventurous lifestyle. David is 72 years old and still owns the hotel with his wife.

Jane (Parker) Matthews: Future mother-in-law

The Rhodesian-born artist married David and had three sons, James, Spencer, and Michael. Michael was 22 years old when he died after reaching the Base Camp of Mount Everest. She and her husband, David, spend much of their time in St. Barts and she's often spotted with her reality star son, Spencer, at various events.
